Building a new rig and stealing my RX 580 for it and putting back my HD 6870 card in my current profile hack.
Using Clover pkg 5102
2 - Apple 20" Cinema Displays (only using one for now)
Downgrading OS to High Sierra from Mojave since old GFX card is not Metal capable.
High Sierra install working great with HD3000 DVI port.
BIOS set to Init Display First > Onboard ( Had it set to PCIx16 with RX 580, but with HD 6870, had to switch it to see POST with DVI onboard )
ISSUE >>
When I boot with DVI cable plugged into HD 6870, the resolution from POST to Clover boot screen is terrible, and login screen only shows 1/4 of the screen. System IS booted, but entire screen not visible. (see images)
Here's the weird part...
If I boot with monitor plugged into Onboard port, no issue... THEN unplug monitor from onboard and plug it right into the HD6870 and BOOM, all is well... Sleep and wake even work.
Here is another thread with the exact same issue, but he never solved it either:
Clover Boot: Screen resolution/partial display/scrambled
Can someone please help me solve this mystery so I can get on with installation in my new Hack?? Pretty please!? And THANK YOU
BTW: I'm using Lilu / Whatevergreen and the HD 6870 is correctly identified in About this Mac window (see image)
My third party kexts are installed in /Library/Extensions and NOT in Clover/Kexts/Other
Config Inject Kexts = Detect
No Graphics / GUI / Framebuffer editing in Config.
If you want me to post my Config, I will tomorrow, but I don't think it's the issue. ( I could most definitely be wrong )
